Identification and Molecular Characterization of Novel Mycoviruses in and Non- Yeasts of Oenological Interest.

Wine yeasts can be natural hosts for dsRNA, ssRNA viruses and retrotransposon elements. In this study, high-throughput RNA sequencing combined with bioinformatic analyses unveiled the virome associated to 16 and 8 non- strains of oenological interest. Results showed the presence of six viruses and two satellite dsRNAs from four different families, two of which- and -were not reported before in yeasts, as well as two ORFan contigs of viral origin.

Phylogenetic Relationship Among Wild and Cultivated Grapevine in Sicily: A Hotspot in the Middle of the Mediterranean Basin.

Grapevine ( ssp. ) is a perennial crop especially important for wine and fruit production. The species is highly polymorphic with thousands of different varieties selected by farmers and clonally propagated.

Short-term effects of potassium fertilization on the hydraulic conductance of Laurus nobilis L.

This study reports experimental evidence on the effect of short-term potassium fertilization on potassium uptake, tissue concentration and hydraulic conductance of pot-grown laurel plants. Potassium uptake and loading into the xylem of laurel seedlings increased within 24 h after fertilization. Potassium was not accumulated in roots and leaves, but the [K(+)] of xylem sap was 80% higher in fertilized plants (+K) than in potassium-starved plants (-K), as a likely result of recirculation between xylem and phloem.
